solenoid valve is. With this technology it is possible to achieve
optimal turbocharger at all speeds.
The aim of a turbocharger
The purpose of a turbocharger is to obtain high torques, and then further performance of the
motor. This is possible by compressing the intake air. Due to the higher density at each stage
Suction can be entered into the combustion chamber of the engine greater
amount of oxygen. The higher content of oxygen improves combustion and is therefore
increase the power.
The thermal energy and kinetic energy of the exhaust gases of the engine is used to operate the
turbine exhaust gas turbocharger. The gas turbine exhaust drives the
compressor. This compresses the air sucked by heating. The air is again
cooled in the intercooler.
Operation
At low engine speeds the vanes of the distributor of the turbocharger are driven
electrically and positioned (i) by depression so that the flow of exhaust gas
impinges on the outer edge of the turbine blades. This causes a narrowing of the flow
of the exhaust gases and leads to an increase of the speed of flow of exhaust gas and the
boost pressure. According to the law of the lever this involves a pair
greater at low speeds.
If the number of revolutions of the engine increases the input section of the exhaust gas is
increased by the displacement of the vanes of the distributor (II). Now the gas particles
more preferably do not affect the outer edge of the vanes of the distributor, but are
distributed along the entire length of the vanes. The turbocharger works with
a lower efficiency, which however is offset by the increased volume of exhaust gas to
high engine speeds.

impregnated with platinum (2), substance catalyzing the oxidation reactions.
Operation
The exhaust gases that pass through the cells heat up the catalyst, triggering the conversion
of pollutants into inert compounds.
The chemical reaction of oxidation of CO, HC, and the particulate is effective with
temperatures between 200 and 350 ° C.
In fact above 350 ° C begin to oxidize the sulfur content in diesel fuel, giving rise to anhydride
and sulfur trioxide.

The variation of this signal allows the coil of EGR moving a shutter,
thereby regulating the flow of flue gases from the exhaust manifold to the intake manifold; is
results in two outcomes:
less air is introduced;
is lowered the combustion temperature (due to the presence of inert gases), reducing
Consequently, the formation of NOx (nitrogen oxides).
The injection control unit is kept informed on the amount of recirculated gas, from
information from the flow meter, for if a certain RPM is expected
the aspiration of a given quantity of air (Qam) and the value sent by the flow meter (Qar)
is lower, the difference (Qgr) is the value of the amount of recirculated gas.
Qam - Qar = Qgr
Qam - theoretical air quantity stored

3.6 Power System
3.6.1 Characteristics
This fuel injection system uses a high injection pressure controlled
electronically, and a mode of delivery of fuel made from an injection
main and one or more pilot injections (according to the conditions of engine operation),
controlled electronically by injection through the electro-
(CR1MI2.2); such a system is able to carry up to five injections cycle (based on
operating conditions of the engine itself).
The pressure value is one of the key parameters for the optimization of
Fuel consumption and exhaust smoke.
The management with more pilot injections makes possible a preheating chamber
combustion in order to avoid the pressure peak caused by a rapid combustion,
ensuring a smoother operation and allows to further reduce emissions.
The adjustment of the injection pressure is possible thanks to the constructive characteristics of the
system that is equipped with pressure pump, pressure regulator, pressure sensor and
electro-separated, all managed by a unit. In this way, the injection pressure
is independent of the speed of rotation of the motor.
The main characteristics of the fuel system are:
high injection pressure of 1400 bar (75 hp) 1600 bar (90 hp)
injection pressure adjustable from 150 to 1400/1600 bar in every working condition of the
engine;
introduction of fuel up to 50 mm3/ciclo in a regime between 100 and 5200
rev / min;
control precision injection and as early as that term;
one or two pilot injections before P.M.S. managed in function of the number of turns and the load
engine that allow you to distribute more evenly the pressure chamber
combustion with a lower noise level.

Features
The high pressure pump is the type CP1 Compact three-piston radial (radialjet). The range is
567 mm3/giro and the speed of rotation being mounted on the camshaft (via coupling
oldham) is equal to half the speed of rotation of the motor shaft (reduction ratio
2:1) and does not require phasing. The pump is lubricated and cooled by the flow of fuel
that runs through it: the flow rate required is supplied by low-pressure pump. This
feeds the pump with an amount of fuel always superior to the needs of
motor in order to create a recirculation of the fuel to the tank, in so doing is obtained
the lubrication (priority) and the cooling of the pump.
The movement of the pistons is determined by an eccentric integral with the pump shaft:
this actuates a polygonal ring which acts on the foot of the plunger.
Each pump unit is equipped with a suction valve to the plate and of a discharge to
sphere.
The pump is equipped with a valve called "shutoff valve": this allows to protect
the pump in the case of low flow from the delivery of low pressure, enabling
maintain lubrication of the compressor pumps and eccentric mechanism

the fuel filter, so the components are individually replaceable.
The electric pump fuel has the function of feeding the high pressure pump. It
is completely immersed in the fuel inside the tank. The pump assembly is
constructed so as to obtain the maximum level of fuel in the area of draft.
This function is realized by means of a venturi located on the return pipe to the draft
compared to that of the tank. The pumping unit is of the type needle roller and allows a flow rate of
160 liters / hour.

Multiple injections:
The strategy of operation with multiple injections allows the control in a precise manner
the combustion process within the cylinder. The injections are modulated to
avoid pressure gradients too high which would cause an increase in the noise
combustion and unnecessary mechanical stress.
Through multiple injections are able to significantly lower the pollutants,
maintaining optimum engine performance. The engine control unit has the potential
to make up to 5 injections per engine cycle known as:
- Injection PILOT
- Injection PRE
- MAIN injection
- Injection AFTER
- POST injection
In this application you can find 4 work areas:
1 injection PILOT PRE + + MAIN
2 + injection PRE MAIN
3 injection PILOT PRE + + MAIN (with dwell time time between the pilot and pre> 1000 usec.)

Operation
Current flows through a semiconductor layer, immersed in a magnetic field normal
(Lines of force perpendicular to the direction of the current) generates at its terminals a difference in
potential, known as tension in the "Hall".
If the intensity of the current remains constant, the voltage generated depends only on the intensity
of the magnetic field; is sufficient so that the intensity of the magnetic field various
periodically to obtain a modulated electric signal, whose frequency is proportional
the speed with which changes the magnetic field. To achieve this change, the sensor
is approached periodically by a tooth formed on the inner part of the pulley.

Potentiometer accelerator pedal
The sensor is constituted by a casing fixed to the accelerator pedal, within which, in
axial position, is placed a shaft connected to the two potentiometers: the main one and of
safety.
On the shaft a helical spring ensures the correct pressure resistance, while a
second spring assures the return of release.
The reading of the redundant signal allows to continuously monitor the plausibility of
measured values, in order to ensure complete driving safety even in case of failure.
Operation
The position of the accelerator pedal is converted into an electric voltage signal and
sent to the control unit from the potentiometer connected to its foot.
The accelerator pedal position signal is processed together with information relating
the number of revolutions to derive the injection timing and the relative pressure.

4 1.4 8 Valve Engine
4.1 Fundamentals
The development of the 1.4 8V has created a shift of 8V Fire engine in cars
segment B and light commercial vehicles. The engine performance is comparable to
Fire 1.2 16V MPI, with better fuel consumption and greater cost competitiveness.
The development of the motor 1.4 8v, has led to a 6% reduction of fuel consumption
(NED) through two actions:
The modification of the valve train with lighter mass and the adoption of valve springs
at low load, reduced fuel consumption by 2%. (NEDC)
The application of the CVCP (continuous variable valve timing) V8 engine helped to reduce the
fuel consumption by 4%
The power and especially the low-end torque of this engine enhance the qualities of
elasticity of the Fiat Punto, ensuring a smooth and ready to shoot without the need for
downshifting, with very good fuel consumption
The adoption of the continuous variable valve timing and a new concept of combustion chamber
variable turbulence significantly reduces fuel consumption and exhaust emissions, especially
in city and suburban.
The new combustion chamber, with a compression ratio increased to 11.0, combined with the
new inlet and exhaust, the new intake manifold and timings of the
optimized distribution, ensures spirited performance, fuel economy and low emissions.
The 1.4 engine complies with the Euro 4.
The main features are most important:
engine in-line four-cylinder OHC 8-valve;
tested in aluminum alloy;

4.3.9 Continuous timing variator CVCP
The Fire 1.4 8v has a continuously variable valve timing (Continuous Variable Cam Phaser), Ie
of a device able to modify, during operation, the position of the shaft to
camshaft relative to the crankshaft in a continuous manner to obtain, so, a variation of the
timing engine.
In this way, at every moment the engine operates with the ignition timing optimal in terms of
fuel consumption.
Approx. 5% reduction of consumption on the NEDC
The phase shifter changes the timing of the engine in the direction of the delay.
Delaying the 'opening of the intake valve and the closing of the exhaust valve, a
part of the intake stroke (greater, the greater is the scalettamento of
phase shifter) is done with closed intake valve and exhaust valve still
open, so that part of the combustion gases are sucked from the exhaust (EGR). These gases are
to occupy part of the volume of the cylinder (reduction of the displacement). To let the
same amount of fresh air and then get the same engine performance
(Same torque / power) at that point of operation, it should be more open the
butterfly. The operation of the engine, at equal performance, with more open throttle
reduces pumping losses that occur in parts of the charge phase (phases exhaust-
intake), thus obtaining a reduction in fuel consumption.

When the crystal is subjected to a pressure or to a collision (B), they are oriented in such a way
much more marked as the higher the pressure to which the crystal is subjected (characteristic
of quartz)
This orientation produces a voltage across the crystal. This voltage is then
result of the vibrations produced by the explosion in the various cylinders.

It is of the inductive type, ie it works by the variation of the magnetic field generated by the
passage of the teeth of the phonic wheel (60-2 teeth).
The injection control unit uses the signal of the rpm sensor for:
determining the speed of rotation
determine the angular position of crankshaft''.
Operation:
The sensor is constituted by a tubular case (1) inside which there is a magnet
Permanent (3) and an electrical winding (2)
The magnetic flux created by the magnet (3) undergoes, due to the passage of the teeth of
phonic wheel, of the oscillations due to the change of air gap.
These oscillations induce an electromotive force in winding'' (2) to the ends of which is to
alternatively find a positive voltage (tooth facing the sensor) and negative (hollow
facing the sensor).

The peak value of the output voltage of the sensor depends on other factors being equal, by the
distance between the sensor and the tooth (gap).
On the phonic wheel are formed sixty teeth, two of which are removed to create a
reference: the step of the wheel thus corresponds to an angle of 6 ° (360 ° divided by 60 teeth).
The point of synchronism is recognized at the end of the first tooth next to the space of two
missed teeth: when this passes under the sensor, the engine is located with the pair of
pistons 1-4 at 114 ° BTDC.
Electrical characteristics:
resistance = 1134 ÷ 1386 ohms at 20 ° C.
The prescribed distance (air gap) to obtain correct signals,'' between the ends of the sensor and the
phonic wheel must be between 0.5 to 1.5 mm.

4.5.16 phase thermal water drainage
The number of revolutions is corrected depending mainly on the temperature of the liquid
engine cooling.
When the temperature reaches the optimal management of the minimum depends only on the signal
coming from the sensor of engine revolutions; to 'inclusion of external loads, the control unit
controls the 'actuator control throttle to adjust engine speed to have occurred
conditions and manage the engine load supporting the minimum.
4.5.17 Management of the fuel vapor recirculation
The strategy controls the position of 'intercettatrice vapor valve as follows;
· During the starting phase the 'solenoid valve remains closed, preventing the vapor
enrich the fuel mixture too; this condition persists until
the engine coolant has not reached 65 ° C;
· Engine electronic control unit sends the temperature regime to 'solenoid signal
square wave (duty - cycle) that modulates the 'opening.
In this way the control unit controls the amount of the fuel vapor sent to '
suction, thus avoiding substantial variations of the license of the mixture.

4.5.18 Management of 'climate
The power-control unit is operatively connected to 'air conditioning system,
as:
· Receives the request for input by the compressor and related interventions
(Additional air);
· Gives its consent to 'insert compressor when the conditions are verified
considered by the strategies;
· Receives' information on the state of the switch operates smoothly and the related interventions
(Radiator cooling fan control).
If the engine is idling, the controller increases the 'opening of the butterfly and therefore of the
scope of the 'air in advance with respect to' activation of the compressor and vice versa shows the
butterfly in the normal position behind the detachment of the compressor.
The controller automatically controls the separation of the compressor:
· For engine coolant temperature higher than 120 ° C;
· To engine speed below 650 r / min.
The compressor will automatically hangs up when the engine speed rises again
750 r / min.

4.5.19 Management of the phase shifter
The phase shifter is completely managed by the engine control unit that:
detects the position of 'camshaft through the phase sensor;
this position changes depending on the operating point of the engine according to a map
calibrated;
keeps under control the position of 'camshaft.
The movement of the phase shifter takes place by means of the pressure of the 'engine oil that
flows in rooms in advance / retard. A spool valve is the flow 'oil or in the receptacle
advance (the drive moves, then, in the sense of 'advance, which is the rest position) or
in vain for the delay (the speed you move, then, in the sense of delay) or alternatively in
those of early and late on an ongoing basis (the drive is controlled position).
The control unit controls the 'solenoid pilot drive with a command of the duty-
cycle.
4.6 Procedures

6.4 ABS system
New Punto comes standard on all versions Bosch 8.0 ABS anti-lock system ill, EBD
(Electronic Brake force Distribution) integrated, which adjusts the braking so
prevent locking of the rear wheels, guaranteeing in any condition the proper distribution
braking action on the axes.
The Bosch 8.0 ABS system is among the most advanced systems available today. The system consists
the following components: an electro-hydraulic control unit with 12 valves, 4 active sensors and 4
channels with offset (or distributor) braking.
The specific characteristics in terms of active safety are:
guarantee to each wheel close to locking, compatibly with the adhesion
available, the highest possible braking
safeguard in extreme situations, close to locking wheels, full control of the car
maximum responsiveness
ability to automatically adapt to different operating conditions
weight of the unit
Active sensors have the function to detect the speed to the wheels.
The fundamental characteristic of the active sensors is that the signal is processed
directly from the sensor.
With the ability to detect very low speeds (2.7 km / h), the active sensors increase the
accuracy of the systems on-board navigation.
The information gathered by the sensors of the ABS assets are also used to update,
through the satellite location system GPS, (Global Position System), the position
car on the maps stored in memory: it is therefore essential to the continued
information, even at low speeds, on the path of the car to calculate the
exact position of the vehicle.

6.5 E.S.P.
L 'ESP, or Electronic Stability Program is an active safety system for the control
of the vehicle in dynamic maneuvers which intervenes in emergency conditions. It 's designed to
correct the trajectory of the car in case of abrupt maneuvers often unintended
increasing, especially on slippery surfaces, active safety. The E. Sp reacts, in fact,
quickly to both the oversteer to understeer of the vehicle and is arranged to return the
vehicle in conditions of stability allowing the driver to maintain full control of the
vehicle.
The system continuously monitors the state of motion of the vehicle (acceleration
lateral, longitudinal and angular speed, adhesion to the ground) and the settings of the driver
(Steering wheel angle, accelerator pedal). If he considers that the car is next to a
condition of instability (skidding, understeer, oversteer, etc..), corrects the motion of the
vehicle by the control of drive torque and braking torque by applying a suitable
separately on each of the four wheels.
The direction control is done by exploiting the longitudinal grip of the tire: the
different braking between the two sides of the car generates a pair of straightening
(Yawing) that stabilizes the car.
The management of the ESP function is entrusted to the ABS control unit that, by processing the values
of
quantities acquired from the various sensors (lateral acceleration, yaw rate sensor, sensor
steering angle, wheel speed sensors and pressure sensors), by means of algorithms implemented in the
software, monitors the parameters of the dynamic control (slip of the wheels, drifts of
axles, trim angle) and interprets any errors committed by the driver carrying
appropriate interventions in order to bring the car back under stable conditions.
The plant consists of the following components:
4 wheel speed sensors installed in special locations on the front and rear uprights
A lateral acceleration sensor and yaw contained in a single device mounted on the
central tunnel;
1 electrohydraulic unit mounted in its holder in the engine compartment;

6.5.3 A.S.R. (Anti Slip Regulator)
It is a function of traction control of the car that is automatically activated in the event
of slippage of one or both driving wheels. This feature is only available with ESP.
Depending on the condition of slip, are activated two different control systems:
If the shift affects both drive wheels, ASR intervenes by reducing power
transmitted by the engine;
if it concerns only a slip of the drive wheels, automatic braking intervenes
the wheel that slips.
The action of the ASR system is particularly useful in the following conditions:
shift in the curve of the inner wheel, due to dynamic load changes or
excessive speeding;
excessive power transmitted to the wheels, also in relation to road conditions;
accelerating on slippery, snowy or icy;
loss of grip on wet roads.
Arming / Disarming A.S.R.
The ASR is automatically inserted at each starting of the engine.
While driving, you can disconnect and then re-insert the ASR by pressing
a switch located between the controls on the dashboard.

with tires 165/70 14 "185/55 15" Point).
Geometry arm front suspension with lower triangular rectangle designed to
separate the effect of braking loads from the cornering ensuring the
best balance in all driving conditions. The new front geometry allowed
also contain the turning circle of the car to values similar to the current model, while
adopting wider wheels and larger pitch.
Suspension, rear torsion beam made with the aim of increasing the
structural rigidity and to increase the flexibility of the suspension under load obtained
by optimizing the bushing connecting bridge to the body. The study of the
new suspension has also affected the shape of the collision in order to
improve the dynamic response when cornering.
Particular attention has been paid in the design of components to address issues
relating to vehicle comfort, adopting technical solutions typical of cars of a higher class,
as the use of the plug dome type "split" ("dual-path") front and
Vertical positioning of the shock at the rear, as this would have allowed
limit the effect of the vibration generated in the road surface,
without altering the structural rigidity at the expense of steering precision.
Increased size of flexible bushes to improve the filtering of road roughness
and increase driving comfort.

9.1 Overview of the system
The technology used for the 'electrical system of the new Punto is based on complex
architecture called "family.1", used for the first time on a FIAT.
Modular plant
To obtain the minimum number of families of wiring, each circuit belonging to a coupling
cutting keeps the same position inside the joint, irrespective of the
trim level; also the position and type of joint on the car is not a function of the
trim level.
To safeguard the modular cables together is expected that the inputs / outputs
for each unit do not differ by trim level / engine, by position
the connector to cable interface / terminal / connector.

9.1.2 Networks and serial lines
Family 1 The architecture, developed specifically for the new Punto, operates the plant
the vehicle's electrical.
For the optimization of the system, the architecture follows the topological approach Regional: each
ECU (electronic or electromechanical) is placed in position with respect to
functions managed.
This allows to minimize the system of distribution of power and signals, even
extended through the use of networks of serial communication, favoring the solution of
problems of size, reliability, weight, cost.

For node includes an electric with a CAN interface.
The more complete structure is composed of two communication networks that connect CAN nodes
belonging to two different areas (dynamic control of the vehicle, and disclosure of
edge / functions of the body), and a serial line complementary "LIN bus" (used for the
first time on a Fiat model in this segment).
The architecture is compatible with various solutions of interfacing user
(Available commands, allocation and how to display information).
The electrical protection (fuses) and the contactors are grouped in units of
distribution of power, position in the engine compartment and dashboard. These units serve
Also from interconnecting the various wiring and electrical distribution.

The more complete structure is composed of two communication networks connected through a CAN
gateway for the transfer of information common:
B-CAN Network for the management of the standard functions of body / infotelematic.
C-CAN network for dynamic control of the vehicle.
The gateway for communication between C and B-CAN-CAN is located in the Nodes Body Computer.
It 'also a serial line LIN communication between the control computer and the Body
control unit of the rain sensor: in this case the Node body computer has the function of
gateway between the serial line CAN and LIN networks.
For the first time on a model Fiat the diagnosis of the nodes, in B and C-CAN-CAN, is realized
via CAN line, using a protocol of the CAN (ISO 14229).

The situation of the architecture diagnostics, both for the control units that are integrated on the network
CAN (nodes), and for those not equipped with a CAN interface, is summarized by the following table:
Some stations and nodes are referred to as "having no diagnosis," although functionality
self-diagnosis (eg, Rain sensor control unit), because it does not have a protocol
Diagnostic implemented and their errors are detected through the diagnosis of
other units (eg BCM).

To the point of diagnosis, establishing a network of serial type CAN HIGH SPEED, is
essential to the new High Speed Cable A16HS. It 'also need to install on Examiner
release 6.30 or later to access all the features.
The interface High Speed Can A16HS is composed of a standard connector EOBD, a
Bantamate female connector (for connection to Examiner) that conttene a circuit
Electronic and LED yellow / green indication of operating status.
Diagnosis and Installation
Insert the interface between High Speed Can A16HS car diagnostic socket and extension cable
Examiner. After connecting the power LED blinks, then blinks green drive.
After activation of the communication with the controller on-line Can the LED remains solid, but
turns yellow. If the LED continuously flashing yellow means there is
was a communication error.
Termination resistors network C-CAN
The termination resistor network C-CAN is present in the ECM and the BCM and has to
both the value of 120 ohms.

Wiping auto mode (rain sensor):.
The rain sensor is activated by moving the ring of the right lever in the position of the stalk
intermittently-automatic. In this way we obtain the adjustment of the frequency of beats of the
wiper according to the quantity of water present on the windshield.
This frequency can vary from no joke (not present rain - dry crystal) up
the second constant velocity (heavy rain - wet crystal).
Activating the rain sensor controls the execution of a stroke of the wipers as
feed-back of insertion of the sensor. The user can vary the sensitivity of the
rain sensor, acting on the menu set-up of car dashboard.
If you turn off the car leaving the ring of the handle to the intermittent-automatic,

9.7.1 General
The security benefits guaranteed by the New Point arise from a careful integration
between the structural components, the high number of specific devices constituting the system
protection of occupants:
- Frontal impact
- Rear-end collision
- Side impact
- Tipping
These results are significantly better than those required to indicate a risk of injury
Occupying virtually nil.
Frontal impact
They evaluated two types of impact between the vehicle in a frontal impact: one made at a rate
of 64 km / h against a deformable barrier representative of a head-on collision between two
cars, one representative of an impact against a fixed obstacle and infinitely rigid, is
done at 56 km / h against a fixed, rigid barrier.
New point is in a position in the event of a frontal impact to hold the load in the trunk
which if not properly restrained can lash out violently against the passengers.
Side impact
The front and rear passenger safety is guaranteed in the new Punto in shock
lateral high speed through two types of main test, the impact,
simulates the impact between two cars running at 50 km / h and the size of colliding with fixed obstacles
reduced transverse poles or trees which are the most dangerous type of collision which can
happen to motorists. Thanks to the robust architecture and the use of structural
materials with high absorption efficiency of energy, of New point the levels of intrusion into

Rear impact
The focus in rear impact tests is addressed, from a structural viewpoint, the containment
of the deformation of the passenger and to the absence of damage to the reservoir that
could cause a fire.
Protection of children
New Step Up also features all the devices that offer maximum
safety for children now feasible. The main devices that make it effective are:

On New Fiat Punto were introduced in the front seat head restraints adjustable for height
with block downhill, which was associated with (optional) the new biomechanical system
antiwiplash. The system antiwiplash intervenes in case of impact as a result of the strong transfer of
load caused by the body resting on the back after the shock and allows the headrest

9.7.2 The Air-Bag Smart 2
The occupant protection in frontal impact is by an innovative restraint system
said Air-Bag Smart 2 as it is able to automatically adjust the parameters of
activation as a function of the severity of the accident.
Air-Bag Front driver and passenger two-stage activation, the consideration
that the existing restraint systems are necessarily sized to ensure
adequate protection in only 10% of the total frontal accidents, have been developed
of Air-Bag double trigger. When the shock is to control the average severity
Electronic controls only the first stage activation of the Air-Bag avoiding the placing of
energy is not necessary for the protection of the occupant. Conversely, for very severe shocks, the
control unit activates both stages in order to be able to absorb the greater kinetic energy
occupant before it impacts against the steering wheel or dashboard.
Front airbags for driver's side: consists of a cushion with instantaneous inflation contained in
a compartment located in the center of the steering wheel.

It represents the heart of the occupant protection system and is located on the tunnel
Front. Simultaneously handles all detection devices and system activation
restraint by processing the signals that come from various sensors throughout the car and
those installed inside which and how many protection devices activate in the event of
accident.
It 's also able to prevent their activation when the collision is not severe enough. A
capacitor, which acts as a reserve of energy, ensures the full functionality of the front Bag
even in the absence of power from the electrical system (when, for example
the collision causes the batteries to rupture or power cables).
The algorithm used for frontal impact situations is called in slang "Crash Severity
Algorithm "as it is able to distinguish whether the collision is medium or high stringency so as to
to appropriately control the activation of Air-Bag-stage.

9.8 The fire protection
In the late 90's with the introduction of new European regulations relating to the crash tests and
with the introduction of the fuel injection system, has become indispensable by
Fiat Auto the need to redefine the design of heavy shell and the
redefinition of lay-out of various systems on the vehicle.
All the Fiat Punto, the various body components, is therefore set to the rigorous
compliance with the latest and strictest internal Fiat safety against fire.
Fire Prevention System - FPS
Of all petrol and diesel is the inertia switch (FPS English
Fire Prevention System) that allows the immediate stopping of the engine a few
milliseconds from the beginning of impact.
The plastic tank, which already meets future directive, is located in a protected area in case of
collision, and the ability to withstand any deformation without risk of leakage
fuel. moreover, being plastic, does not generate risks of explosion in case of fire
car.

be redundant, and therefore is not installed on your system.
The adjustment is based on the value of suction pressure, according to the following logic:
low pressure, the displacement of the compressor tends to the minimum value;
high pressure, increasing displacement.
This control logic refers to the following practical conditions:
"Low pressure" means that the load imposed on the air conditioner is not of sufficient magnitude to
require a high flow rate of fluid.
"High pressure" means that it imposes a significant burden to the climate and the amount
necessary for the cooling fluid is high.
Operation
The motion of the pulley is continuously trasmeso the shaft of the compressor by means of
jumpers called "limiter" (3) which have the function, in the event of seizure for failure of the
compressor, to stop allowing the pulley does not stop and thus not
break the auxiliary belt.

10.4 Diagnosis
Procedure proxatura unit
Through appropriate control logic of the sensors and control with "self-learning"
of the actuators, the control unit is able to record and store a series of anomalies and
faults that may occur in the system.
You can read the errors stored by connecting to the diagnostic socket of the Body
Computer.
This operation is used to make the system learn the position of end of stroke of the actuators
of electric air conditioning unit.
Using computerized diagnostic equipment, activate the prescribed procedure.
This operation must be repeated with the substitution of at least one of the actuators.
In case of interruption of the procedure.

Pressing the button (opening side), with a Key-ON, allows two modes of opening
Glass front panel:
Automatic: Through a normal button press on the "open" (for a time
> 300 ms), completely enclosed by glass panel front door "to open spoiler"
(Ensuring less wind noise), then pressing on the same
side of the button, the front glass panel is brought into position of maximum opening. After the
Initial command to open the glass panel can be stopped at intermediate positions
pressing the button again.
Manual: By a short press of the button (for a time 60 <T <300 ms), from
completely closed, the front glass panel moves in proportion to the time T
press the button and stops in position to release the button. With pressures on

in the closed position. After an initial command to open the glass panel can be stopped
in intermediate positions by pressing the button again.
Manual: By a short press of the button (for a time 60 <T <300 ms), from
fully open the front glass panel moves in proportion to the time T
pressure on the button between 60 <T <300 ms and stops in the release position of the
button; with pressures on the same side of the button later and always in the time
T between 60 <T <300ms, the panel will move in increments until it reaches the position

11.2.3 Shades
The adjustment of the brightness inside passenger compartment is allowed through the use of 2 tendon
parasol: one for the movable panel front and one for the fixed rear. The tendon
Polyester is sun, each slide and roller blind, with shoes
sliding, avoiding the undermining of the guides. Their openness is manual and can
only be fully open or fully closed. The closing of the curtain
Parasol is independent of the opening position of the front panel.
11.3 pinch and closing the roof
The system of anti-pinch, managed by the electronic control unit, as well as being consistent with
as required by Directive 2000/4/EC, is active during closing horizontal and vertical
front panel after meeting an obstacle (eg finger, hand):
in the horizontal motion of closure is active throughout the entire stroke (if it is open more than 4
mm) and in
Following the meeting of an obstacle on the front side of the panel glass, ensures the inversion
of motion for a stroke equal to 100 mm from the point of inversion motion;
in the vertical motion of closure is active (if open more than 4 mm from the wire seal), following
encounter an obstacle on the rear side of the panel glass ensures the inversion of the
motion until it reaches the open position of a compass.
In both cases, the load that determines the reversal is <100 N, as required by Directive
2000/4/EC. The possibility of pinching from inside the vehicle in the lateral zones of the panel
is avoided by the adoption of side shields that prevent access to danger areas.
